Petunia plant named ‘Sunsurfpiusi’

ABSTRACT

A new and distinct cultivar of  Petunia  plant named ‘Sunsurfpiusi’, characterized by its compact and mounding plant habit; vigorous growth habit; freely branching habit; early and freely flowering habit; long flowering period; medium-sized purple-colored flowers; and good garden performance.

Botanical designation: Petunia×hybrida.

Cultivar denomination: ‘SUNSURFPIUSI’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Petunia plant, botanically known as Petunia×hybrida and hereinafter referred to by the name ‘Sunsurfpiusi’.

The new Petunia plant is a product of a planned breeding program conducted by the Inventors in Higashiomi, Shiga, Japan. The objective of the breeding program is to create new upright and outwardly spreading Petunia plants with freely branching habit and attractive flower coloration.

The new Petunia plant originated from a cross-pollination made by the Inventors in September, 2005 in Higashiomi, Shiga, Japan of a proprietary selection of Petunia×hybrida identified as code name PxBR, not patented, as the female, or seed, parent with a proprietary selection of Petunia×hybrida identified as code name Px262-99, not patented, as the male, or pollen, parent. The new Petunia plant was discovered and selected by the Inventors as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Higashiomi, Shiga, Japan in September, 2006.

Asexual reproduction of the new Petunia plant by terminal cuttings in a controlled environment in Higashiomi, Shiga, Japan since October, 2006, has shown that the unique features of this new Petunia plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Petunia have not been observed under all possible environmental conditions and cultural conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Sunsurfpiusi’. These characteristics in combination distinguish ‘Sunsurfpiusi’ as a new and distinct Petunia plant:

-   -   1. Compact and mounding plant habit.     -   2. Vigorous growth habit.     -   3. Freely branching habit.     -   4. Early and freely flowering habit.     -   5. Long flowering period.     -   6. Medium-sized purple-colored flowers.     -   7. Good garden performance.

Plants of the new Petunia can be compared to plants of the female parent selection. Plants of the new Petunia differ primarily from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Petunia flower earlier than plants of the         female parent selection.     -   2. Plants of the new Petunia have larger flowers than plants of         the female parent selection.     -   3. Plants of the new Petunia and the female parent selection         differ in flower color as plants of the female parent selection         have darker-colored flowers.

Plants of the new Petunia can be compared to plants of the male parent selection. Plants of the new Petunia differ primarily from plants of the male parent selection in flower color as plants of the male parent selection have lavender-colored flowers.

Plants of the new Petunia can also be compared to plants of the Petunia ‘Sunsurfcoparu’, disclosed in U.S. Plant Pat. No. 18,141. In side-by-side comparisons conducted in Higashiomi, Shiga, Japan, plants of the new Petunia and ‘Sunsurfcoparu’ differed primarily in the following characteristics:

-   -   1. Plants of the new Petunia had smaller and darker         green-colored leaves than plants of ‘Sunsurfcoparu’.     -   2. Plants of the new Petunia were more freely flowering than         plants of ‘Sunsurfcoparu’.     -   3. Plants of the new Petunia had larger flowers than plants of         ‘Sunsurfcoparu’.     -   4. Plants of the new Petunia and ‘Sunsurfcoparu’ differed in         flower color as plants of ‘Sunsurfcoparu’ had red purple-colored         flowers.     -   5. Plants of the new Petunia had larger sepals than plants of         ‘Sunsurfcoparu’.
